WASHING APPARATUS FOR M'ILKZENG-M ACHZ'INE IPART'S.

Ap lication filed November To all whom it 'litttfi/ 001mm:

Be it l'GIOW'n that I, WILLIAM E. S11E11; wool), a citizen of the U'i'i'ited States, residing at 'Cana'stota, in the county of Madison and State of New York, have invented certain new and useful Improvements in Washing Apparatus for Milkin -lilachihe Parts, of which the following is a specification.

' The present invention relates niore particularly to apparatus for washing the parts of millzing machines, and the object is to provide a relatively simple mechanism that is comparatively inexpensive so as to be Within the reach "of the ordinary farmer, and by means of which certain essential parts of milking machine can be effectively cleansed.

One embodiment of the invention is illustrated in the accompanying drawings, wherein l Figure 1 is a rear elevationof the apparatus, V

Figure 2 is front elevation of the same,

Figure is a vertical sectional View,

Figure 4c is a top plan View,

Ii -igm-e 5 is a detail view in elevation 01 the operatiii-g mechanism,

- Figure '6 is detail sectional yiew through one of the shaft mountings. i

111 the embed inent disclosed, aliquid tank or container 7 is employed'sup orted in a I suitable frame 8 and preferably constructed of sheet metal. It has an open top, a bottom 9 that inclines downwardly in one recti'on, and valveddrain 1O coninlunioab ing with its lowermost portion. v

Journaled in the rear side allll ot the tank or container a plurality of horizontally disposed shafts l2 and 13, these shafts being eferably of dilferent len ths and extending; in parallel relation toi'vard the front side of the tank or container 7 Each shaft is provided with a liquidaight hearin and this hearing is shown in detail Figure 6. A. head yoke 14, located outside the container, is provided with a bushin 15 eX- tending' through the rearwall 11, and hawing its inner end threaded. A holding nut 16, screwed upon said inner end, abuts against the inner sideot the wall 11, and thus clan'ips the head and bushing in place. The not it will be observed, projects beyond the inner end of the bushing, aiid threaded ings in order to clamp s, parts 9, 1921. Seria1 N o.514,043.

intothe said projectingend, is a'plug- 17 be"- tween which and tile inner ehd ofthe bushing is interposed packing 18. The shaft extends through the bushing plug, and said plug 17, hut l6 an'd packing 18 provide a acking gland. V

The outer ends of the shafts have suitably secured thereto pulleys 1 9 located within the yokes 14, and passing around said pulleys is a transmission belt 20-, the ends of which are fixed to the ends of a CllfVGd: belt track 21. This track is mounted on the upperend of a lever 22-, and ispreterably formed of sheet metal having side arm braces 23 thatextencl to opposite sides of the lever and longitudt nally along said opposite sides. The upper end of the leverextendslto' the central portion of the track 21, and is secured thereto as illustrated at 24, thus torniihg a support.

The fasteners for the ends *of the belt are illustrated at 25, and may be of any suitable characten 1e1 e'1'ehce to F 5,it Will be noted that the two intermediate shafts and pulleys are located at a loi'ver-level than the end pulleys and that the belt passes on the inner sides of the intermediate pulleys, then over the same and around the outer sides ahd over the outer pulleys; The lever 22 is fulcrumecl at 26, to the frame, and pivotall'y I connected to the loweren'cl of said lever at 27 is planar-128 eon-heated to the crank 29 of a drive shaft 30." This drive shaft is mounted the frame andis provided with a suitable pulley 31, by which motion from any suitable source can be imparted thereto In the construction shown the lever '22 has its lower portion lon itudinally split, as shown at 32;, and is provided with bushings 33 for the fulcrum 26 and pivot 27, holiest being located on opposite of said bushtogether. 4 r

In certain inilkingflnaehihes there is em ployed a relatively long flexible tube th'iot'ig li which the milk passes, and which must therefore be thorou hly cleansed in order to be sanitary; Means are therefore rovided for cleaning such tubes. This means oon'sists'of a relatively long shaft or spindle 35 detachably fixed in any suitable manner to the shaft 12, and carrying a brush or scraper 36 which is located in or securely adjacent to the inner end of a guide tube 37 fixed to the front side of the container and having an upturned inlet end 38. The other shafts 13 are provided with suitable detachable brushes 39 which may be of various sizes as desired, to enter the different instrumentalities and openings or pockets of the parts.

lVhen power is delivered to the pulley 31, Y

it will be evident that the lever will be given a rocking motion and the belt 20 thereby drawn back and forth overthepulleys 19, imparting rotary motion to the shafts l2 and 13 alternately in opposite directions. The shafts and brushes are located below the normal liquid level, so that in actual operation they are submerged.

The operator standing at the front of the machine can therefore place the different parts upon these rotary brushes, and they are cleaned below the liquid level. The flex- .ible pipe is inserted through the guide tube 38, and is passed over the brush or scraper 86 as far as it will go. It can then be reversed and the other end passed over in like these brushes operate below the level of the liquid it causes an excessive agitation. This is due to the fact that when the brushes rotate in one direction, the liquid is caused to rotate with them. The sudden stop and reverse rotation of the brushes isagainst the rotary current thus produced, thereby (ill breaking up such current and causing great disturbance thereto.

From the foregoing,-it is thought that the construction, operation 'and many advantages of the hereindescribed invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size,

shape, proportion and minor details of con-- struction, may be resorted to WltllOlll) do parting from the spirit or sacrificing any of the advantages of the invention. H aving thus fully described my invention, what I claim as new, and desire to secure by Letters Patent ist- 1.
